' elevated by the lever a and the cam c3 moves .s structed' in accordance .with lmy invention y 1S not likely to get out of repair and does not yrequlre as high a degree of skill for its con- 'Weight on the pendulum and, obviouslly an A seat lever o. is pivoted at d2 on the rear l of the bowl and a seat A is hinged thereon. Said lever extends rearwardly and engages beneath a collar a? on the lower end of the rack bar C and normally holds the seat in an inclined position, as shown in Fig. 2.

If referred, and as shown in Fig. 2, a stop arm is rigidly engaged on the bar within the casing, and pivoted on a suitable lug e on the front of the casing is a lever e', the inner end e2 of which engages beneath said arm and is adapted to normally raise said bar. A stop e3 is carried on the bottom of the casing and is adapted to be engaged by the end' e2 of said lever and limit the downward movement of the rack-bar.

The operation is as follows: When the seat is forced down onto thebowl the rack-bar is `above the roller b2. During the upward movement of said bar the spring c2 is compressed and the pinion d and the 'ratchet wheel d? rotate loosely on the shaft d. As soon as the weight is removed fromv the seatr the spring c2 acts to force the bar downwardly and the pawl d4 engages the ratchet teeth and by ldriving the chain o f gears operates the pendulum which serves to regulate the downward speed of the rack-bar. As the rack-bar descends the pressure of the cam c3 on the roller b2 acts to force the hinged section b of the valve stem downwardly into alinement with said stem and forces the stem inwardly,' thereby opening the valve and iiushingthe bowl. As soon as the cam c3 has passed below the roller b2 the stem moves outwardly and again closes the valve.

` When it is desired to manually operate the valve the lbar is elevated by means of the lever e and the flushing operation is performed as before described. Obviously the downward s eed of the bar, and consequently the interva during which the valve is held open, may be regulated by adjustinrY the automatic valve operating mechanism construction as does the fiuid controlled valves.

Obviously -also many details of form and construction `may be variedy Without departing from the principles of my invention.

claim as my invention:

l. In a device of the class described the combination with a valve of a jointed, slidable valve stem therefor, a longitudinally movable b ar adjacent said stem adapted to operate thefvalve when moved in one direction, means on said bar adapted to bend the l stem when the'bar is moved in the opposite direction and means adapted to regulate the speed of saidbar during its operative movement.

2. In a device of the class described the combination with a valve of a slidable, jointed valve stem therefor, a longitudinally movable bar adapted to operate said valve -stem when moved in one direction and to throw it out of operative position when moved in the other direction, means adapted to move said bar to operate the valve and adjustable means adapted to Aregulate the movement thereof.

3. In a device of the class described ,the combination with a valve of a jointed valve stem. therefor, a longitudinally movable bar adjacent said stem and having a camthereon adapted to operate the valve whenthe'bar moves in one direction and `to throw the valve stem out of operative position when the bar moves in the opposite direction, means-adapted to move said bar to operate the valve, a pendulum supported adjacent .the bar and means operatively connecting said )endulum with said bar and adapted to regu ate the speed of the bar.

4. In a device of the class described the combination with a valve of a jointed valve stem therefor, a roller on the outer end of said stem, a rack-bar supported adjacent said stem' and having a cam thereon adapted to engage said roller, means ada ted to elevate said bar, means adapted to ower said bar and force the valve stem inwardly, and clock mechanism adapted to control the lowering movement of said bar. i

5. In a device of the class described the combination with a casing of a rack-bar therein and projecting outwardly therefrom, a cam on said bar, a valve sup orted adj acent said cam, a slidable jointedj valve stem in said valve adapted to be forced inwardly by said cam when the bar is moved in one direction and to be bent at its oint when the bar is moved in the opposite direction, and a clock movement in said casing adapted to move the bar for a given interval.

6. In a device of the class described the combination with a casing of a rack-bar I thereinand projecting therefrom, a pendulum pivoted in said casing, gears connecting said pendulum `with said. rack-bar, a spring adaptcdto move the bar outwardly, a valve adjacent said bar, a jointed stem on said a cam on the projecting end of said bar, a valve supported adjacent the same, a slidable valve stem on Said valve having a hinged section 0n its outer end adapted to In Witness whereof I have hereunto 'subturn upwardly when the hm' is moved toward scribed my name in the presence of two Witthe easing, aJ roller on said section adapted to nesses.
